GARBAGE-INCINERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 588,998, dated August 31, 1897.

Application file d November l5, 1895, Serial No. 569,091. (No model.)

Be it known that I, J EREMIAH J. KENNEDY, a citizen of the UnitedStates', residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Garbage-Incinerating Apparatus; and' I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

This invention relates to apparatus for destroying garbage, including all kinds of vegetable and animal refuse, carcasses of animals, &c. and also burnin g the noxious gases, vapors, and odors given oif from garbage in the incinerating operation.

The object of my invention is to provide for economically heating air by the Waste heated products from the garbage-furnace and utilizing such heated air for drying garbage and absorbing the vapors and odors aris-V ing from the body of garbage being burned .and then supporting combustion of gaseous or other fuel by means of such heated air containing the noxious vapors and odors, thereby effecting .at the same time the combustion of the fuel and the vapors and odors contained in the air with which the garbage has been treated, and then utilizing the resulting hot products to effect the combustion of the solid portions of the organic substances to be destroyed.

Another object of my invention is to provide an effective and economical construeA tion and arrangement of furnace or furnaces adapted to iirst consume all the vapors and odors given off by the garbage charged into it and at the same time utilize the calorific value of the garbage burned for heating the air which is used for absorbing and carrying to ,the fuel-combustion furnace the vapors and odors from the body of the garbage being burned. Y

The gases, vapors, and odors given off during the operation of incinerating garbage escape from the fresher and cooler portions of the charge and are not destroyed by simply raising them to a hightemperature and permitting them to escape into the stack, as is customary.

In my apparatus airis first heated to increase its capacity for absorbing the moisture in the garbage and for absorbing and carrying off the vapors and odors. It is then passed in contact with the cooler and fresher portions of the charge of garbage to drive off the moisture and to absorb the watery and combustible vapors and offensive odors, which are then carried to the fuel-furnace or COmbuStiOn-chamber, where the vaporcharged air supports combustion of gaseous,

ing the combustion of the vapors and odors and the development of great heat. The resulting flame and hot products are passed in I contact with the solid portions of the garbage to be destroyed,thereby consuming them with the development of additional heat. The heat developed by the above operation is then utilized Vto heat the air required to dry the body of garbage and absorb the vapors and gases given oif therefrom or given off from succeeding charges of fresh garbage. The operation of the apparatus is thus made continuous and effects a great saving in fuel, since theproducts of combustion finally pass off at a low temperature.

Garbage containing fat or animal matter when acted upon by the heated air gives off large volumes of rich oily vapors, which are absorbed by the air and carried to the furnace or fuel-combustion chamber,where their combustionV takes place', resulting in a saving of fuel required to destroy the solid parts -of the garbage.

In conducting the operation the escape of vapors and noxious odors from the apparatus is also prevented and their destruction effected by passing or drawing currents of cold air in contact with the fresher and cooler por! tions of the charge of garbage and then using such vapor-charged air for causing combustion of the fuel required to destroy the solid portions of the garbage in the manner above described. I prefer, however, to use heated air, for the reason that it will more readily drive off the moisture and absorb the vapors and odors and for the further reason that the capacity of suoli heated air for absorbing and carrying vapor increases rapidly with its temperature.

My improved apparatus is illustrated in the accompanying drawings, in whichliquid, or solid fuel, at the same time effect- ICO Figure l represent-s a vertical longitudinal section of one form of my apparatus arranged to burn gas or hydrocarbon vapor for fuel. Fig. 2 represents a horizontal section thereof on the line a, Fig. l. Figs. and 4 represent vertical transverse sections, respectively, O11 the lines y y and 2, Fig. l. Fig. 5 represents a vertical longitudinal section of a portion of another form of my apparatus arranged to burn solid fuel inthe fuel-Combustion chamber. Fig. (5 represents a vertical transverse section thereofl on line fw 1r.

In my apparatus l preferably use a gas generator or producer A, in which gas is generated and delivered to the fuel-con'ilnlstion chamberof thegarbage-furnace. The generator A is constructed of brick and inclosed within an iron jacket or shell in the usual manner and is provided at the bottom with the usual ash-pit B, grate Z), and the fuel and ash openings a.' and a, closed by lids or doors su' and fr". The generator is provided at the top with a fuel-supply opening a and a closing-lid a: and also with an escape flue or pipe C, connecting with the garbage-furimce. An airblast pipe V, having a valve c, leads from a blower \\v and connects with the ash-pit, and a steam-supply pipe S, having a valve, connects with blast-pipe Y for supplying steam,

with air, to the generator. By means of the air-blower and the steam-supply pipe connecting as described gas can be generated and delivered under pressure to the fuel-combustion chamber of the garlnige-furnace. Though l preferably generate and supply gaseous fuel to the fuel-combustion chamber, I may also obtain good results by constructing a tire-box for solid fuelin the fuel-combustion chamber of the garbage-furnace, as illustrated in Figs. and t5, or by using a separate furnace connecting with the combustion-chamber.

rl`he garbage-furnace E is constructed with thick walls F. and E for containing the necessary gas and air flues and is provided with the usual grate d, dividing it into the combustion-chamber D below and the garbagechamber F above. A downtake-liue C in the end wall E' connects the gas-outlet pipe C of the generator with the fuel-combustion chamber D through the port c, adjacent to the airinlet portsfl, as shown in Figs. l and S.

The end wall lil is constructed with the vertical air-inlet ilues fand the end wall E is constructed with the vertical air-fluesj, as shown in Figs. 2, 3, and i. The inletluesj'are provided with dampcrsj, as shown in Figs. l and i, and the discharge-fines f are provided with the dampersj for closing their openings when desired. The inlet-fines 6o and discharge-{luesf/ f are connected by the horizontal pipes 71.

The pipes L are placed near the side walls of the garbage-chamber F, as shown in the drawings, andare for the purpose of conducting hot air through the garbage-chamber to heat the garbage and drive otf the watery vapors and volatile parts of the charge. The

pipes 7L also support the body of garbage laterally a short distance away from the side walls, so that a larger surface is exposed to the drying and absorbing action of the air which is passed in contact with the surface of the body of garbage.

The channel-bars 7L' pass through the garbage-chamber and have under their ends, at one end of the garbage-chamber, air-inlet ports s, connecting the garbage-chamber with the air-lues ff and have under their ends, at the other end of the garbage-chamber, outlet-ports s, connecting the garbage-chamber with the luesff. These channel-bars are for the purpose of maintaining channels or passages through the body of garbage under the entire length of each bar for the passage ofthe hot air through and in contact with the body of garbage to dry it and to absorb its moisture and volatile constituents.

As the hot air passes through the ports .5 connecting the garbage-chamber with the air-fines ff and through the body of garbage along the under sides of the channel-bars 7L to the outlet-ports Sl, connecting the garbagechamber with the iluesf'fQ it also heats the channel-bars and dries the garbage in contact with their upper surfaces.

The form of the channel-bars may be varied to obtain the best results with the kind of garbage being destroyed, but for kitchen garbage I prefer to use the form shown.

Any number of vertical courses of channelbars may be used, provided they are spaced horizontally a sufficient distance from the airpipes and from each other to prevent them from acting asa grate and to insure a column of garbage between adjacent bars.

The continuous downward movement of the body of: garbage, due to the combustion of its lower surfaces, causes every part of the charge to be acted upon by the currents of air passing in contact with the outer surfaces or through the channels in direct contact with the garbage.

Feed-openings c, having tight-closing lids c', are 'provided at the top of garbage-ineinerating chamber F.

Lateral openings u and It are constructed in the side walls of furnace E for giving access to the grate and to the fuel-combustion chamber l) for removing ashes, tbc.

The coinbustion-chambcr D and the garbage-chamber F are connected, respectively, with the air-heating stove G by means of the lower ilue d and the upper flue g.

The air-heating stove G is constructed with double end walls, forming air-inlet flue g and outlet-flue g. The stove G is also divided by a transverse partition-wall 7n, extending from the bottom thereof to near the ytop and forming the connecting-eompartments G and G" for causing the hot gaseous products to travel up and down through the chamber in contact with the air-heating pipes m. rl`hese pipes m are placed horizontally and connect the air inlet flue g with the air-outlet flue g', as shown IOO IIO

in Figs. l and 2. An escape flue or opening d for products of combustion in the outer end wall of air-heater G connects by the pipe Zwith the eXhauster L, which in turn connects by an outlet-pipe Z' with the stack P. An airinlet pipe V', extending horizontally above nace, so that offensive vapors and odors which might arise from piles of garbage adjacent to the said openings will be drawn into air-pipe V and conducted through the air-heating stove to the garbage-incinerating chamber F.

Platforms X are constructed on a level with the top of the garbage-furnace for permitting carts or wagons to be hauled alongside of the charging-openings e, so that garbage may be dumped directly into the chamber F.

The apparatus having been constructed and connected as above described and substantially as illustrated in the drawings may be operated as follows: A fire is kindled upon the grate of the generator and is supplied with fuel until a deep body of ignited fuel is formed. Combustion of the fuel isv preferably urged by an air-blast from blower W,

and after a sufficient body has been heated to incandescence steam is .supplied through pipe S and a good fuel-gas generated and delivered under pressure to the combustionchamber D. The escaping hot products pass through the air-heater G and are drawn off by the eXhauster L. As soon as the exhauster is set in motion air will be drawn through pipe V', and thence through the air-heating stove G into the -garbage-chamber F, and thence through the flues f to the gas-inlet port c, where combustion of the gas is eifected. At any suitable time, either before heating up the apparatus or afterward, a body of garbage is charged into the chamber F and subjected to the drying and absorbing action of the currents of hot air from the heating-chamber, by which the vapors and offensive odors will be absorbed and carried into the fuelcombustion chamber, where they will'be completely consumed by combustion of the fuelgas with the vapor-charged air. The resulting iiame and hot products will burn and destroy the garbage lying upon grate d, resulting in the development of additional heat, whichwill pass off with the products of combustion and highly heat the air, which is drawn through the heating-pipes m in the airheating stove G.

In the above operation part of the air may be passed through the pipes 7L and the channels hby partly or wholly-opening the dampers j and partly closing the dampers j', and all the air may be passed through the pipes h and channels h by entirely closing the dampers j and opening the dampers j.

The operation may be made continuous by keeping the exhauster L and the air-blower W in operation.

Since a separate blower is used for supplying air under. pressure to the gas-generator, the operation of generating gas and supplying it to the, combustion-chamber will not beinterrupted when the lids e at the top of the garbage-chamber are opened, as would be the case if I depended upon the exhauster alone for drawing air into the gas-generator as well as drawing air through the heater and in contact with the body of garbage. If I exhausted air through the gas generator as well as through the air-heating apparatus and garbage-furnace, the generation of gas and combustion thereof would cease whenever the covers of the charging-openings of the garbage-chamber were removed-to introduce an additional charge, since then the whole volume of air would be drawn by the eXhauster directly through. the charging-opening into the garbage-chamber and no air would be drawn through the gas-generator. No gas would then be made and air only would be drawn through the garbage-chamber, causing a rapid lowering of temperature of the fuelcombustion chamber, and the air with its vcharge of vapors and odors would be passed -notwithstanding the fact that one or more lids ofthe charging-openings are removed.4

Fig. 5 represents a vertical longitudinal section of a good form of my apparatus arranged toburn solid fuel.

Fig. 6 represents a vertical transverse section on the line w w, Fig. 5.

Similar letters of reference in Figs. 5 and 6 represent similar parts in Figs. l, 2, 3, and et.

The furnace A is constructed in the usual manner with a bridge-wall O, grate b', resting on bars h", ash-pit B', and fuel and ash openings o and o', closed by doors p and p.

This apparatus may be operated as follows: Solid fuel is delivered upon the grate b and ignited, and combustion maintained by air drawn through the apparatus by the eX- hauster L. At any suitable time, either before or afterheating up the apparatus, garbage is charged into the chamber'F and exposed to the action of the currents of air. After acting on the body of garbage the air with its charge of vapor and odor is drawn through the flues f f into ash-pit B', then up through the furnace Al to support combustion of the fuel on the grate b', and at the same time consuming all vapors and odors. The hot products of combustion are then drawn through the combustion-chamber D to effect the-combustion of the solid portions of the garbage and develop additional-heat for heating the air passing through the air-heater G.

It will be observed that in my apparatus it` IOO IIO

is impossible for vapor, odor, or product ot' iiues connecting the garbage-chamber with combustion to pass from the apparatus except through the fuel-furnace and thence through the exhauster, and since all vapors and odors are burned in the combustion of the fuel, With the air carrying them, it is impossible for vapors and odors to escape unconsumed from the apparatus.
